To all w hom t may consci/Ta:

Be it known that l, EUGENE SCHNEIDER, aciti'zen of the Republic of France, and a resident of Paris, France, have invented new and useful Imprcvments in Guns Meunted on V'Vheeled Carriages, which invention is fully set forth inthe following speciication.

Wheeled gun carriages are known which are so constructed as to provide a limited range of lateral movement of the carriageV Vhead of the onn carriage instead of slidinor D C 7 D upon the wheeled axle, is slidably mounted on a cross-piece or auxiliary axle elastically supported on the main or wheeled axle. Interposed between the main andV auxiliary axle are springs to carry the gun and its carriage during transport, and means are provided for connecting the carriage directly with'the main axle during iring so that the shock of discharge will .be transmitted directlyA` from the carriage to the main axle without the interposition of the.

suspension springs.

In my copending applicationtiled October 24E, 1919, Serial No. 333,101, several con-V structional forms of this invention are shown and described, and the present appli-y cation isa division of `the earlier application, being directed to one of the constructional forms therein disclosed.

In the accompanying drawings, in which similar reference charactersdesignate copr-l responding parts-l p Figure 1 is a view,lpartly in elevation and partly in vertical section,on the line 1-1 of Fig. 2, of a constructional form of the invention;

Fig. 2 is a vertical section on the line 2-2 of Fig. 1;

y Fig. 3 is a horizontal section on the li-ne 3 3 of Fig. 2; i Y l Fig. 'vll is a vertical section on the line 1 4 of Fig. 1. Y

According to lower ends to form guide-jaws to engage the this constructional form the invention, the straight main axle A is carried by the wheels B in the usual manner, and supported in offset parallel relation to such axle and approximately in the same horizontal plane is the straight auxiliary or false axle F, on which is mountedthe carriage C to slide laterally thereon. 0n each end of the auxiliary axle is journaled a bracket 0, held against lateral movement thereon by the collar f, f 'of the axle. Seated in the socket 0 in the top of each bracket in the upperr bow of the leaf spring I,- the two bows of which are connected at their ends by the'links H. The lower bow of the spring is seated in a socket of the block 'G mounted on the main axle between the collars a, a of the axle, the collars preventing lateral movement of the block on the axle, rllhe main axleis rectangular in cross-section and the block G, fitted thereon, is prevented 'from turning. rllhe block so right. Forming part of the bracket O and on opposite sides of the same are the stirrups O2 engaging the main axle to limit the vertical play of the bracket and attached snrino relatively to the axle. The stirrups have a sliding engagement with theopposite vertical sides ot the axle which tends to hold the bracket and the attached spring in upright position. When the springs I are tree to act, they provide an elastic suspension for the carriage that can be 'utilized in trans'- port of the gun.

Means are provided for guiding the'carriage C in its vertical movement relatively to the main axle A`while suspended bythe springs" l` duringtran-sport, and also for rigidly vconnecting the carriage to the main axle duringiiring se that the shock'ot1 olischarge will be transmitted directly from the carriage to the main axle without, the interposition of the springs. Y

Fixed to opposite sides of the carriage C are the cheek-blocks C2 'recessed at their opposite flat sides of the main axle A As thecarriage is moved along the auxiliary axle F,the cheek-blocks slide along the main axle. The recesses in the cheek-blocksare sufficiently deep to permita limited upward movement therein of the main axle as,

thewheels B ride over obstructions in the road during transport, the interposed Patented New. e, ieee.V

serine-s I carrvinf the load and ieldinU to A i: J C b the movement of the main axle. While the cheek-blocks permit relatively vertical movement, to a limited extent, between the carriage and main axle, yet they maintain such parts in their proper spaced relation and the two axles in approximately the same horizontal plane during such movement. lVithout these cheek-plates, the carriage and brackets I would buckle downward on the auxiliary axle F until the main axle A. jammed against the carriage.

In the upper ends of the recesses in the cheek-blocks C2 are the bearing plates K swiveled to the lower ends of the bolts L threaded through the upper ends of the cheek-blocks. By turning down the bolts L, the plates canbe forced onto the main axle A to form a direct bearing for the carriage on the axle. With the plates so adjusted, the springs I will be relieved of the load and, during firing, the shock of discharge will be transmitted directly from the carriage to the main axle. By turning the bolts L upward, the bearing plates are raised from the main axle and the carriage will be suspended by the springs I for transi port purposes.

The cheek-blocks C2 on the carriage and engaging the main axle A and the brackets on the auxiliary axle and also engaging the main axle form-traction connections between the carria e and main axle, so that a pulling or'pushing force imparted to the carriage will be transmitted to the main axle and its supporting wheels.

In placing the gun for firing, the tail of the carriage trail (not shown) is pivoted to the ground in the usual manner. Preliminarily to firing, the bolts L are turned down to force the plates K onto the main axle A to form a direct bearing between the carriage and the mainaxle and thereby relieve the springs of the load. In training the gun, the head of the carriage is moved along the auxiliary axle by a screw (not shown herein,

l Y but disclosed in Figs. 2 and 4 of the parent case) journaled in the carriage and engaging a nut on the auxiliary axle. When the head of the carriage is adjusted on the auxiliary axle, the carriage as a whole will pivot on the anchored tail of the trail. As the gun is so trained, the movement of the carriage head will cause a slight shifting in the position of the main axle relatively to the trail pivot and the supporting wheels will turn slightlyto accommodate this shifting of the main axle. Preliminarily to transport, the carriage is moved to a midway position on'the auxiliary axle and the bolts L are turned upward to raise the plates K from the main axle so that the load will be suspended by the springs. What is claimed is:*

In a gun mounting, a wheeled main axle, an auxiliary axle yieldingly supported on the main axle in offset parallel relation thereto and approximately in the same horizontal plane with said main axle, a carriage slidable on the auxiliary axle for training the gun, and adjustable means operative to form a direct bearing for the carriage on the main axle to relieve the auxiliary axle of the load and to transmit the shock of discharge directly from the carriage to the main axle. j
